ThinkSystem SR860 Maintenance Manual
Supports multi-core Intel Xeon processors, with integrated memory controller and Intel
Ultra Path Interconnect (UPI) architecture.
• Two processor sockets (expandable up to four) with minimal requirement of two
installed.
• Designed for LGA 3647 sockets
• Scalable up to 28 cores
• Supports Intel Extended Memory 32/64 Technology (EM32/64T)
Notes:
• When server installed with two processors, only 4U PCIe riser assembly 2 is
supported.
• When server installed with two processors and two AnyBay backplanes, 4U PCIe
riser assembly is not supported.
• When server installed with four processors and two AnyBay backplanes, only one 4U
PCIe riser assembly is supported.
• Minimum: 16 GB
• Maximum:
– RDIMM: 1.5 TB
– LRDIMM: 3 TB
– 3DS-RDIMM: 6 TB
Note: Some types of GPU require the total installed memory to be less than 1 TB.
For specific types of GPU, see:
• DIMM types:
– PC4-21300 (single-rank, dual-rank), 2666 MT/s, error correcting code (ECC),
double-data-rate 4 (DDR4) registered DIMM (RDIMM)
– PC4-21300 (quad-rank), 2666 MT/s, error correcting code (ECC), double-data-rate
4 (DDR4) load reduced DIMM (LRDIMM)
– PC4-21300 (octa-rank), 2666 MT/s, error correcting code (ECC), double-data-rate
4 (DDR4) three-dimensional stacking registered DIMM (3DS-RDIMM)
• Slots: 24/48 DIMM slots, two-way interleaved
Sixteen 2.5-inch drive bays:
• Eight 2.5-inch hot-swap SATA/SAS drive bays (bay 0-3, 8-11)
• Eight 2.5-inch hot-swap SATA/SAS/NVMe drive bays (bay 4-7, 12-15)
Two types of drive backplane:
• 2.5-inch SATA/SAS 8-bay backplane (referred to as "8-bay backplane")
• 2.5-inch AnyBay 8-bay backplane (referred to as "AnyBay backplane")
Four types of 4U PCIe riser card:
• ThinkSystem SR860 1x16 PCIe FH riser 2
• ThinkSystem SR860 2x8 PCIe FH riser 2
• ThinkSystem SR860 1x16 PCIe FH riser 3
• ThinkSystem SR860 2x8 PCIe FH riser 3
Note: NVIDIA V100 GPU is supported only when two 2000W power supply units are
installed in the server and all processors are less than 200W.
